HeyGen just launched its next-gen AI engine: Avatar IV.
With it, your avatar doesn’t just talk like you — it moves like you.
Real gestures, expressions, pauses, rhythm — all captured.
At Singularity, we make high-clarity engineering videos fast but they're not that good. But now with this upgrade our videos has improved.
That shift came from one upgrade: HeyGen’s Avatar IV engine.
After testing across our scripts, here’s why Avatar IV stays in our stack:
Real movement: Your avatar captures your actual body language not just face, but hand gestures, facial expressions, even eye movement.
Emotional tone: Pauses, pacing, rhythm, all there.
One-shot training: A 2–5 minute video is all you need to start.
No actor, no retakes: Once trained, your avatar delivers new videos instantly.
This isn’t a talking head generator. It’s a full-body mimic of you, deployable on command.
No tool is perfect. Here's what to know before diving in:
Only 7 minutes of video per month on free plans
What you film is what you get: bad lighting, weird speech = bad avatar
No edits allowed: you need one continuous, natural take
You still need to act natural: overact and your avatar overacts too
For what it is — a scalable, realistic video tool — the pros still massively outweigh the cons.
How to Create Yours (Step-by-Step)
Here’s the quick-start for engineers or marketers:
Record a 2–5 minute clip of you speaking naturally.
Upload to HeyGen → Avatars → Create Digital Twin
Wait for a couple of mins for processing
Done. You can now generate videos just by uploading scripts.
You can also change outfits, styles, or scenes.
Pro tip: Even if you plan to replace the voice, your training clip must have your real speech. It’s how lip sync works.
For Singularity, video creation has always been painful time-consuming, awkward, often inconsistent. Avatar IV fixes that.
